如何以编程方式将背景颜色从android.support.design更改为MaterialButton
问题描述：
我尝试使用以下代码将颜色更改为MaterialButton:
I try change color to MaterialButton with this code:
var materialButton = findViewByid(R.id....) as MaterialButton
materialButton.setBackgroundColor( ContextCompat.getColor(this@MyActivity, R.color.myCustomColor));
使用普通按钮，它可以工作.有人有什么想法吗?
With a normal Button, it works. Anyone have any ideas?
答
我找到了如下答案:
我更改了以下行
materialButton.setBackgroundColor( ContextCompat.getColor(this@MyActivity, R.color.myCustomColor));
到
materialButton.setBackgroundTintList(ContextCompat.getColorStateList(this@MyActivity, R.color.myCustomColor));
我以这种方式进行了测试，并且效果很好.
I tested it that way and it worked perfectly.
